CONVEYER.

.lippncation med August as, 1922.

To al? whom t may oon-oem:

Be`it known that l, AUGUST J. Rnsroon, a citizenof the United States, and resident of the city of St. Louis and State of Missouri, have invented certain new and useful improvements in Conveyers, of which thev following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in conveyers, and has for: its primary object a conveyerv` in which the head is so mounted that it can swing pivotally and allow the supporting frame to rest securely at both ends regardless of lthe inclination of the floor longitudinally of the conveyer.

A further object is to construct a conveyer in which the head can be adjusted forfhorizontal alinement regardless of the lateral inclination of the fioor.

A still further object isto construct a conveyer in which the head is pivotally mounted on standards, the standards being made adjustable so that the height of Vth head from the tioor can be varied.

In the drawings.

. Fig. 1 is a side elevation of one form of conveyer with my improvements applied thereto. j

Fig. 2 is a top plan view of the saine.

Fig. 3 is a top plan view of the standards with the head removed.

Fig. 4 is a perspective view of one of the head supports or crossheads. I

Figs. 5 and Gare top plan views of the legs out of which lthe standards are constructed. Y

In the construction of my device, I employ standards 7 and 8; the lower ends of these standardsare provided with bases, 9 which have bolt openingsrfor securing the same to a floor or foundation. The upper end of the standard 7, 4is provided with ears 10 which are spaced apart and between which the. ear 11|, formed on the upper end of the standard 8, iits. rlhese ears are provided with openings so as to permit the shaft 12 to pass therethrough. Mounted on f the shaft 12 and between the standards are cross heads or head supports 13; these head supports are provided with the downwardly extending portions or bosses 14 through Which the shaft 12 extends. The cross heads are further provided with recesses 15 and secured within these recesses are angle Serial N'o. 584,246.

irons 16; these angle ironsV project upward from the cross heads and are provided with angle irons 17 to which journal boxes or bearings 18 are secured. Within these bearings is located shaft 19 on which is secured a roller 20; this rollermay be either smooth or may be in the form of a sprocket wheel, depending entirely upon the kind of conveyer used. The shaft 19 extends beyond one of the journals 18, and has at tached thereto, either a pulley or gear wheel not shown, which in turn is connected to any suitable source of power. Secured to the angle irons 16 are angle irons 21, 22

.and'23; the angle irons 21 and 22 serving as a rest or support for the apron 24, while the angle iron 23 acts as a guide orI guard for the articles being. conveyed and prevents them from slipping away from the conveyer. The lower or oppositeends of angle irons 2,1, 22 and 23, are secured to angle irons 25 which form the frame work of the tail and Within the tail are slidably secured boxes or journals 26 in which a shaft 27 is carried. yThis shaft has secured thereto a roller or sprockets not shown to hold the lowerend of the conveyer.

The tail is also provided with adjusting screws 2 8, the purpose of which is to give the proper tension to the apron or sprocket chains and to take up unnecessary slack. The standards 7l and 8 are alsoy provided with ears 29 in which-rods 8O are secured; the free end of these rods are secured within .a turnbuckle l31, the purposel of these rods and turnbuckle being to draw the bases of the standards closer together or spread them apartV by means of which the shaft 12, and

consequently the head, is raised or lowered.

The standards are further connected by tiebars 82 which tend to stiften the baserand prevent side rocking.

By the use of my device. it is possible to make a standard ,head Vand by supplying legs of various lengths to this head, the same can be'raised any distance above the floor.

I am vfurther enabled to adjust lthe height of the head by merely bringing together or spreading apart the bases. The horizontal alinement can be secured by the independent adjustment of the standards on one side of j the machine; this is necessary where the floor inclines laterally while the longitudinal inclination of the floor is automatically taken care of by the pivoting of the cross heads.

In the present type of onreyer, it is essary that the head be built special Jfor every job and the supports of the head carefully measured t0 tak@ Cl'e. of the, inclinan tion of the oor either laterally or longitudinally oi the conveyer. lf this is not done, it will be necessary to level up the floors of the building where the .-eonveyer is nsed, but in either case a considerable loss of time and the piling up of useless cost of installation is necessary. Y

l have also found it preferable to pivot vthe feet 9 on the standards 7 and 8, so that they will always rest solid yon the base, regar-dless of the inclination of the standards, as l have found by experience that when the bases .or leet 9 are formed 'integral with the standards, the adjustment of the stand ards to .and Vtrom each other, cause these eet either to rest on the toe or heel; and consequently do not give a solid foundation as is the Case when they are pit/totally mounted. Y

Having fully described my invention, what I claim, is:

l. A conveyor comprising a pair ot A final-nes, a s'hat carried by said frames, a eonveyer head pivotally mounted on said shaft, `and means earried 'by said A frames for moving the lower ends of each frame to and from each other.

A oonveyer comprising a pair of A frames adjustable independently as to height, means carried by each of said trames whereby its adjustment is accomplished by moving the lower ends thereof to or from each other, a shaft earried by said frames at their upperv ends, and a oonveyer head pivotally mounted on said shaft. BfA conveyer comprising a plurality of standards hingedly Connected together in pairs at one fend, means located intermediate the ends of each pair for adjustment of the lfree end of saidV pairs of standards to and from each other, a shaft carried by said standards at their hinged end, and a pivotally mounted conveyer head Carried by Said Shaft- 4- A conveys' @villprsins' e Pair 0f Standards provided at their upper ends with an @ya a shaft extending through Said eyes whereby Said standards are Hnsedly @0n- ,nsted together in pairs, nlwisarried by steh air bf ,standards for moving the free ends. ,o and from .each other Wheifeby Said standar-ds. may he adjusted in pairs as to height, and a convey-er rhead pivotally mounted on said shaft and between said pairs of standards.

'l A conveyer comprising a plurality of standards having an eye formed on one end, a shaft extending through said eye for connecting .the standards together in spaced apart pairs, means carried by each pair of standards for moving the free ends of each pair of standards to and from each other, whereby said shaft may be raised .or lowered and a conveyer :traine pivotally mounted on said shaft and between the standards.

A oonveyer comprising a plurality of standards vhaving an eye formed .on one end, a shatt Yextending t'hnough said eye for oonneeting the standards together in spaced apart pairs, a turnbuckle carried by each pair ot' standards for moving the tree ends of each pair to and from .eaeh other, and a eonveyer frame pivotally mounted .on said shaft and between the standards, and feet pivoted to the fine ends .of each Aof said standards.

7. A eonveyer ycomprising a plurality of standards having an eye formed .on .one end, a shaft extending thnough said eye for oonnecting the standards together in spaeed apart pairs, means- Vcarried by each pair Aof standards for moving thefree ends of each pair lto and from `eaoh other, for raising and lowering and leveling said shaft and a conveyer frame pinotally mounted `on Jsaid shat and betweenthe standands, and tie 4hars tor securing said standards against side sway.

8. A conveyer comprising a plurality of standards having an eye formedon one end, a shaft extending through said eye for ennnecting the standards together in spaced apart pairs, meansearried by eaeh pair of standards for moving/the free .ends ot eaeh pair to vand from each other, for leve-ling said shaft and regula-ting its height and a eonveyer traine pivotally mounted on said shat and between the standards, and feet pivoted to the free ends of said standards, said feet being rovided with openings to permit the passageV .of fastening means therethrough, and tie `laars for secuning said standards against side sway.

In testimony whereof, I have signed my name to this speciiication.
